Piston Slap: Need a “Hans and Franz” ABS Workout?

Craig writes: Sajeev, Some time ago I purchased a 1995 (E36) BMW M3 as a project car. Mostly I have limited myself to bringing the maintenance up to date. I have a more than averagely equipped workshop and can find my way around a car pretty well (I have even built my own Brunton SuperStalker) One problem that has eluded me from day 1 is an intermittent ABS light. Should I just ditch the ABS forever or is there a way to trouble shoot these things without Hans and Franz at the stealership taking me for a ride? Sajeev answers: I tend to like ABS, especially for a car that's so race course worthy.  The E36 M3 is just a fantastic car in so many ways.  That said, I was disappointed when I googled Brunton SuperStalker and realized it wasn't a murdered out full-size van with a suped up turbo diesel motor, air-ride suspension and big ass wheels. A non-van referred to as a SuperStalker?  That's almost criminal! Right.  So, about the diagnosis, you have two options.  The first is spending a lot of time on the BMW forums, learning how to diagnose this vintage system and possibly finding a common problem with a somewhat easy to fix solution. Not really your cup of tea?  Then find an independent mechanic that specializes in BMWs and get 1-2 hours of their diagnosis instead.  It will be worth it. The dealership isn't the best move here, usually. Cars that are "E36-old" need a shop that is tailor-made to their unique needs.  Many (insert make here) dealerships know a good vintage (insert the same make here) shop and will recommend them to anyone. Yes, I've seen it happen! Most importantly, Hans and Franz will always encourage you to work your ABS. "Hear me now, and believe me later: WORK YOUR E36 ABS!  ARE YOU A GIRLY MAN?"    Send your queries to sajeev@thetruthaboutcars.com.
